how do you prove that sinx/(1-c0sx) (1-cosx)/sinx=2cscx(1 c0sx)?

Please note that you can't copy-and-paste equations from another application into this web site. I thought you might have meant this:

$<br /> \frac {\sin x}{(1 - \cos x)}\ + \ \frac {(1- \cos x)} {\sin x} = 2 \csc x(1+ \cos x)<br />$

But actually:

$<br /> \frac {\sin x}{(1 - \cos x)}\ +\ \frac {(1- \cos x)} {\sin x} = 2 \csc x$

Please repost your question and make sure it appears correctly.
